Mistletoe is a green plant that can make its own food, but also derives food from the mesquite tree on which it lives. In this way mistletoe is able to steal water and valuable minerals from the tree. 1. What is the advantage and disadvantage of this relationship to each organism? 2. What would happen to the mistletoe population if mesquite trees increase in number? 3. What type of symbiosis is this?
Answer:
1. Mistletoe is parasitic to the mesquite tree, it steals from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.
2. If the mistletoe population on the tree were to increase, the mistletoe would probably end up slowly killing the tree. I say this because its a parasite to the tree. Its constantly stealing water and valuable minerals that it needs and doesnt give back anything that could help the tree. With all the water and minerals being stolen and an uneven rate with no way for the tree to replenish it all quickly enough it'll die.
3. Its parasitic since the mistletoe just takes and takes harmfully
Mistletoe plant is a parasite on the mesquite tree as it takes all the valuable minerals and water from the plant and does not give anything valuable in return to the mesquite tree.

i need help with this can someone help me?
Explanation:
Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

How are the reactions of photosynthesis and Cellular respiration interconnected?
The reactions of photosynthesis and cellular respiration are interconnected, as the glucose produced by photosynthesis is consumed by animals in cellular respiration.
What is cellular respiration?Cellular respiration is a process of breaking down of food material into simpler forms in releasing energy.
Because oxygen and glucose are produced during photosynthesis from carbon dioxide and water, while water and carbon are produced during cellular respiration, the reactants of photosynthesis and cellular respiration are linked.
The ATP, which is energy transferred as a result of that process, results in the transmission of both water and carbon as byproducts.
Therefore, as the glucose created by sunlight is used by animals during cellular respiration, the reactions of photosynthesis and cellular respiration are interrelated.

The primary reason that osteoporosis accelerates after menopause in women is: * 2 points A. Increased osteoblast activity. B. Reduced levels of vitamin C. C. Diminished osteoclast activity. D. Reduced levels of circulating estrogens.
Answer:
The correct answer is D. Reduced levels of circulating estrogens.
Explanation:
Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.

C)Fusion reactions can proceed in any temperature range.
D)Fusion reactions are easier to control and regulate.
Answer:
B)Fusion reactions do not produce harmful radiation and transuranium nuclides.
Explanation:
___________
The benefit of utilizing fusion reactions instead of fission reactions is that the fusion reaction does not produce harmful radiation and transuranium nuclides. Thus, the correct option for this question is B.
What is meant by Fusion?Fusion may be defined as a type of process that significantly involves the combination of two or more atoms or molecules in order to form one larger molecule. This type of reaction normally occurred in nature as compared to fission.
The process of fission involves the disintegration of numerous smaller molecules or atoms from a larger one. This creates a lot of long-lived radioactive substances in nature that are harmful to live organisms. These types of reactions are not favored by nature.
Therefore, fusion reactions do not produce harmful radiation and transuranium nuclides are the benefit of utilizing fusion reactions instead of fission reactions. Thus, the correct option for this question is B.

After swimming in the pool for 2 hours, your friend starts to complain because his fingers and toes are wrinkled. Use the concept of osmosis to explain why. Be sure to include the following in your explanation: The terms hypotonic, isotonic, and/or hypertonic (as well as what they mean) • The overall direction of water movement and reason why • How the movement of water causes his fingers and toes to change • A picture if necessary
Answer:
Explanation:
Osmosis is the spontaneous movement of molecules from low concentration to high concentration. The finger is hypertonic to the swimming pool, which means that it has a higher osmotic pressure. The pool is hypotonic to the finger, which means it has a lower osmotic pressure. Because osmosis goes from low to high concentration, water will seep into the finger, causing it to swell and become wrinkly. This balances out the concentration on both sides of the semipermeable membrane (skin on the finger) and makes them isotonic, meaning they have the same concentration.
